Blacks are okay, I've known some very nice black people, it's n*ggers that are the problem, and good black people, the ones that are just trying to make a living and live their lives will be the first to tell you that because they are often dealing with the plague of n*ggers in the neighborhoods first. Anyway, at most times n*ggers are simply a nuisance, ruining the quality of life for a community, and at worst, randomly, they are criminal and dangerous.
But arabs ARE OUR MORTAL ENEMIES, and not just of the Jewish people and Israel, the are the MORTAL ENEMIES of all Western Civilization and humanity. The majority support the terrorists, the support for the terrorists ranging from simply being sympathetic to them, all the way to giving massive direct material support to the mass-murdering terrorists. Then there are the actual arab terrorists. So no contest as far as I am concerned. Arabs are far more evil.
